Mechanical Properties of Cold Mix Asphalt (CMA) Mixed with Recycled Asphalt Pavement
نویسندگان
چکیده
From the perspective of sustainability and environmental concerns, use cold-mix asphalt (CMA) recycled pavement (RAP) is more advantageous than hot mix (HMA) warm (WMA). Some researchers used a mixture CMA RAP to improve mechanical properties made it economical. However, only few studies have focused on using high content RAP—particularly 100% RAP—as virgin aggregate. Therefore, this study aims analyse instead aggregate raw materials determine best for production environmentally friendly asphalt. It necessary investigate performance mixed with in terms resilient modulus, indirect tensile strength, fatigue rutting resistance. In study, percentage bitumen emulsions added 2%, 2.5%, 3%, 3.5%, 4%, along material. The results indicate that life increased by 49.34% addition emulsion (BE) from 2% while wheel tracking test experienced decrease depth an increase BE dose which was 9 mm. containing 4% has performance. suggested increasing dosage increases resistance against fatigue.

Evaluation of the Mechanical Properties of the cement treated Cold-in-Place Recycled Asphalt Mixtures
Cold-in-place recycling (CIR) is an environmentally sustainable alternative for preservation of asphalt pavements. A major disadvantage of this practice is the lower strength of the cold-in-place mixtures. Addition of cement into this type of mixture is a method for increasing its bearing capacity. The effect of cement content on the mechanical properties of the cold-in-place recycled asphalt m...

The asphalt paving industries are faced with two major problems. These two important challenges are generated with an increase in demand for environmentally friendly paving mixtures and the problem of rapidly rising raw materials. Recycling of reclaimed asphalt pavement (RAP) is a critical necessity to save precious aggregates and reduce the use of costly bitumen. Warm Mix Asphalt (WMA) technol...
متن کاملPerformance of Recycled Asphalt Shingles in Hot Mix Asphalt: TPF-5(213)
US transportation agencies have been increasingly using recycled asphalt shingles (RAS) in hot mix asphalt (HMA) applications over the last 25 years. Initial use of RAS started with recycled postmanufacturers shingles, but now agencies are showing a growing interest in using post-consumer (tear-off) RAS in asphalt applications. Post-consumer asphalt shingles typically have 20 to 30 percent asph...
